Severe Weather Today


Severe weather is already starting to break out across the southern Planes this afternoon due to a low pressure moving NNE along a frontal boundary. This low is pulling heat and humidity northward and packing some jet stream energy which will allow storms to develop and become severe. Here is what is expected to happen today/tonight:
-Clusters of thunderstorms will continue to develop across Texas and Oklahoma this afternoon. These will likely produce severe hail and high winds. There could be some embedded super cells due to the jet stream energy and strong surface based cape which will will create a tornado threat especially in Texas/Oklahoma this evening as this is where an area of stronger jet stream energy will be and where instability will be the highest. These areas of storms could form into more of a derecho type event overnight tonight.
-Other storms will occur farther north in the warm sector as it will be very unstable and there will also be a strengthening jet stream. The storms farther north may be a little less widespread but still could be pretty strong.
-Severe weather will continue tomorrow and Friday. More on this later.
